Comparative Study of the Immunogenicity of MMR (Measles, Mumps and Rubella) Single Dose and Multidose Presentations

Phase 4

Completed

• Conditions: Measles; Mumps; Rubella
• Interventions: Biological: MMR Vaccine

• Registration Number: NCT01777529
• Lead Sponsor: The Immunobiological Technology Institute (Bio-Manguinhos) / Oswaldo Cruz Foundation (Fiocruz)

Brief Summary

Whether the lower immunogenicity of the mumps component obtained in clinical studies with the MMR in Brazil, due to the multidose presentation. Investigations were made on factors that could interfere with immunogenicity of mumps component, as the kits used for the immunoassay method, and potency of the vaccine, but no explanation was found. This study aimed to investigate the hypothesis that the lower immunogenicity of the mumps component of the MMR Bio-Manguinhos vaccine, is due to the multidose presentation.

The Main objetctive is evaluate the immunogenicity of MMR after one dose in children 12 to 23 months of life, comparing the performances multidose vial (10 doses per vial of vaccine produced in Bio-Manguinhos/Fiocruz through technology transfer from GlaxoSmithKline Laboratory - GSK) and single dose vial (1 dose per vial of vaccine produced by GSK).

Detailed Description

Study Design

This is a clinical trial Phase IV, randomized, single-blind, with two arms:

* MMR (TV) combined measles, mumps and rubella vaccine produced in Bio-Manguinhos, applied to healthy children 12 to 23 months. Multidose presentation, only from one batch.

* MMR (GSK-TV), produced by GlaxoSmithKline, the same age. Monodose presentation, only from one batch.

Locations of the study

* CMS Heitor Beltrão - Tijuca

* CMS Milton Fontess Magarão - Engenho de Dentro

* CMS Waldyr Franco - Bangu

Non-inclusion criteria

• Children with a history of measles, rubella and or mumps.
• Having previously received MMR vaccination documented in book (eg in situations of conducting national campaign or blocking vaccination before suspected cases of the disease).
• Have received injectable vaccines of live attenuated (eg. Yellow fever vaccine) - in this case, defer vaccination with MMR after 30 days of the last live attenuated vaccine administered.
• Having received a transfusion of blood or blood products, including immunoglobulins, less than 1 year.
• Skin lesions at sites of venipuncture.
• Child subject to abnormal bleeding after injections.
• Use the last 6 months in immunosuppressive doses of corticosteroids and other immunosuppressants.
• Fever or the day of inclusion in the 3 days prior to the inclusion in this case may be rescheduled for inclusion after 14 days the fever subsides.
• Use of antibiotic on the day of inclusion or in the last 7 days prior to the date of inclusion - in this case, may be rescheduled for inclusion after 14 days of the last day of antibiotic use.
• Any significant abnormality on physical examination the day of enrollment.

Primary Outcome Measures

Name	Time	Method
Whether the lower immunogenicity of the mumps component obtained in clinical studies with the MMR in Brazil, due to the multidose presentation.	42 days after vaccination, blood samples will be done to determine the levels of antibodies to all three components of the MMR Vaccine	Before vaccination study and about 42 days after, shall be taken blood samples to determine the levels of antibodies to all three components of the MMR (measles, mumps and rubella). Antibody titers are measured by enzyme immunoassay (cut off point of 231 units/ml for mumps, 4 IU/ml for rubella and 150 IU /ml measles) and neutralization test plaque reduction for measles (cut off point of 0.20 IU/mL for measles).
